Description
MOTU 1248
Feature Summary
Superb audio quality
For example, the balanced TRS analog outputs produce a 123 dB dynamic range and -110 dB THD+N (0.0003%) at -1 dBFS, Unweighted, 1 kHz.
66 simultaneous audio channels
4 mic inputs, 2 guitar inputs, 8 x 12 balanced analog with dedicated main and monitor outs, 2 x 8-channel ADAT optical, RCA S/PDIF (with SRC), and two independent phone outs for 32 inputs and 34 outputs.
Universal connectivity
Connects to a computer with Thunderbolt, standard AVB Ethernet, or audio class-compliant high-speed USB 2.0 (compatible with USB 3.0 and iOS). Discovery app and web app software works alongside any host audio software.
On-board DSP with mixing and effects
Flexible 48-input digital mixer modeled after large format mixing consoles, with 12 stereo busses and DSP effects, including reverb, 4-band EQ, gate, and compression.
32-bit floating-point processing
The 1248’s mixing and effects DSP engine deliver virtually unlimited headroom and the utmost in sound quality.
Modeled vintage effects processing
Classic reverb. Compression modeled after the legendary LA-2A compressor. EQ is modeled after British analog console EQs.
System expansion and audio networking
Add a 2nd MOTU AVB interface (1248, 8M or 16A) with a simple Cat-5e ethernet cable. Connect up to five MOTU interfaces using a MOTU AVB Switch (sold separately). Build a network with multiple interfaces and computers using standard AVB switches and network cabling, with ultra-low network latency, even over long cable runs (hundreds of meters). Stream hundreds of audio channels among devices and computers on the network.
Matrix routing and splitting
Flexible, matrix-style audio routing and splitting for any analog or digital input, computer channel or network stream to any other output, computer, or network device. Split any single input to unlimited multiple output destinations.
256 channels of network audio I/O for your host computer
Record and monitor up to 128 networked audio channels in and out, simultaneously, through the Thunderbolt connection to a host computer.
Web app control
Control on-board DSP, mixing, device settings, and network audio routing from web app software running in your favorite browser on a laptop, tablet or smartphone connected by wire or Wi-Fi to your local area network.
Stand-alone mixing with wireless control
Connect an Apple Airport™ or other Wi-Fi router directly to 1248 with a standard Ethernet cable and control the 1248’s powerful mixing and DSP effects from your smartphone or tablet, without a computer. Great for live sound mixing.
ADAT digital I/O
Connect outboard digital processors, digital mixers or other gear. 16 channels at 44.1/48 kHz or 8 channels at 88.2/96 kHz.
Comprehensive metering
The large backlit 324 x 24 LCD lets you view all signal activity at a glance with detailed metering for all analog and digital I/O. Access hardware settings from a simple and convenient menu.
AudioDesk
Includes AudioDesk workstation software for Mac and Windows with 24-bit recording, sample-accurate editing, and 32-bit mixing and mastering.
